To @Z5 when@ z may concern:

Be it known than l, Giur; Gerson, of Cei-lsruhe, in che Grond Duehy of Baden ond Enipire of Germs-ny, have invented certain new and useful improvements in Sewer-Gates, of which the following is n speciontion.

The moin defects of the sewergetes used heretofore ore that i-hey do noi; close tightly, and thereby the water is drained od from the mud, sediment, 85o., ab the gele, thus necessitoting the removal of seid deposits of sedinient, mud, life., quite frequently. n

The object of my invention is to provide a new and improved server-gate which is devoid of those defects, closes tightly, permits no noter to poss and drain off l'roni the sediment, end which gete is simple in construction and effeobive in use, and not api; to get out of order.

ln the accompanying drawings, Figure l is a fase view of my improved sewer-gate, the ports for actuating the gate being shown in section. Fig. 2 is o cross-sectional vievv of the gute, the saine being closed. Fig. 3 is e top view of the easing in which the mechanism forshifting fhe gelte is looeted, ports being broken oui; and ozhers in section, Fig. i is o side View of one of the gates, the seeb for the gate ond ports of the guides for the seine being in section. Fig. 5 is n fece View of my improved gate, showing a modified Consbroetion oi1 seid gate, also showing one of seid gnidesin crosssection.

Similar letters of reference indicate corresponding parts.

The gir-te B is made in onyvell-l; nown ninnner, and is provided Wit-h side logs, Z and Z', which :ire mounted to slide in the verticallygrooved guides o, which ere united el; their upper ends by n crosspiece, el, and no their lower ends by o enrved cross-piece, B, thus forming e tight end rigid frame, the piece B being shaped the seme as the bottoni edge of the sliding gate B, so es to forni e sent against which said gele can di; snugly. The erosspiece B is also provided with an outwardlyprojecting ilenge, (j. The lugs l and l are slightly beveled, as is shown in Fig. 4, and adj eeen@ to seid lugs the guidepieees in in m2 are provided,u The guide-pieces m ond me foce the beveled sides of the lugs l and Z', and the beveled side of the guidepieee m' feces the straight ieee of the lug l.

When the gate is moved downward, the bevels of the lugs Z end Z Work on the bevels of the guidepieees or end fm?, respectively, whereby the lower port oi' the gate is pressed snugly and firmly against. the erosspieoe forniing the seat.

The erosspieee Bend the sent-freine of the seine and the lower ports of the gate should be mede of brass or any other suitable metall that is not attacked or destroyed by he liquids in the sewers. The lug Z serves to move the gate outward While the sinne 1s being raised,

so es to avoid undue friction.

The gate is provided at iis lower end with a strong cuttingedge, k, which is beveled to Ward the seat formed on the cross-piece B', :is shown in Fig. 2, so that when the gere is lowered. the beveled pero of the cutting-edge een strike obstrue'ions and move them to one side or the other or sever rhein, so as not to interfere with closing che gate completely. The flange g, previously mentioned, is below said cutting-edge. From the top of the llenge y a slight incline extends to the bottoni of the sewer. As soon as the gate begins to rise the bottoni lugs, l', strike the beveled sides of the guide-pieces in', whereby the edges of the gate ere slightly moved from the seat, thus preventing the edges or sides that forni the tight; Joint from sliding on enen oher.

An ordinary worm or sereiv mechanism is used 'for shifting the gebe. The Worin or screw u is journnled in the eross-pieee lend engages with a ruck, o, formed or secured on the sliding gate. The Worm n is screwed or other- Wise secured on the shefig ,'Whieli projects upward, and has its upper end squared for receiving o, key, by ineens of which the shaft; can be turned, said squared end being located in e easing, K, embedded in the pervemeniJ in the usuel manner, so that the position of the gate can readily be determined. Anindioeting apparatus is provided in the easing K, and consist-s of the soresT fr, mounted in the casing and driven from the shaft i by inea-ns of nwo oogwheels. A pointer is screwed on the screw r, and es the screw i is revolved the pointer is moved upward or downward, and this indicates or shows the relative position of the gate. The worm wheel or sorew a is contained in a suitable casing of the cross-piece d, for the purpose of preventing the worm being clogged up by dirt or sediment or other deposits which are likely to oeeur within the sewer.

Smaller gatessucli, for example, as shown in Fig. 5-can be operated directly by hand without the interposition of the screw device. The gates are provided with upwardly-projeeting rods, with which chains, 1evers,or other devices for lifting the gates ean be connected.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. In asewer-gate, the eombination,with the two grooved guides and a gate sliding between them, of cross-pieces uniting the guides at the top and bottom, a flange on the bottom of the cross-piece, and a beveled cutting-edge at the bottom part of the gate, substantially as set forth.

2. In a sewer-gate, the combination, with the guides ce, having beveled guide-pieces m m2, 0f a gate mounted to slide between grooved guides and provided with beveled lugs ZZ',

substantially as shown and described.

3. The combination, with grooved upright guides having the beveled guide-pieces m m m2, the guide-pieces m m2 being at the same side, the guide e and the guide-piece m at the opposite side, of a gate mounted to slide between the guides c and having the beveled lugs Z Z, the bevels of the lngsZ Z facing the bevels of the guide-pieces m m2, and the bevel ofthe guide-piece m facing the straight side ofthe lug l', substantially as set forth.

4. The combination,withavertieally-guided sewer-gate, of a screw for moving the same and. a screw-indicator operated by the shaft
